1. What Lamotrigine Tablets are and what they are used
for
Lamotrigine tablets belong to a group of medicines called antiepileptics. They are used to treat two conditions – epilepsy and
bipolar disorder.
Lamotrigine tablets treat epilepsy by blocking the signals in the
brain that trigger epileptic seizures (fits).
• For adults and children aged 13 years and over
Lamotrigine tablets can be used on their own or with other
medicines to treat epilepsy. Lamotrigine tablets can also be
used with other medicines to treat the seizures that occur
with a condition called Lennox-Gastaut syndrome.
• For children aged between 2 and 12 years
Lamotrigine tablets can be used with other medicines, to treat
the same conditions as above. They can be used on their
own to treat a type of epilepsy called typical absence
seizures.
Lamotrigine tablets also treat bipolar disorder. People with
bipolar disorder (sometimes called manic depression) have
extreme mood swings, with periods of mania (excitement or
euphoria) alternating with periods of depression (deep sadness
or despair). For adults aged 18 years and over, Lamotrigine
Tablets can be used alone or with other medicines to prevent
the periods of depression that occur in bipolar disorder. It is not
yet known how Lamotrigine tablets work in the brain to have this
effect.

Tell your doctor if you are taking any of these.
Some medicines interact with Lamotrigine tablets or make it
more likely that you’ll have side effects. These include:
• valproate (for epilepsy and mental health problems)
• carbamazepine used to treat epilepsy and mental health
problems
• phenytoin, primidone or phenobarbitone (for epilepsy)
• risperidone, used to treat mental health problems
• rifampicin (an antibiotic)
• a combination of lopinavir and ritonavir or atazanavir and
ritonavir (to treat Human Immunodeficiency Virus infection)
• hormonal contraceptives, such as the Pill (see below).
Tell your doctor if you are taking, or if you start or stop taking
any of these.
Hormonal contraceptives (such as the Pill) can affect the
way Lamotrigine tablets work.
Your doctor may recommend that you use a particular type of
hormonal contraceptive, or another method of contraception,
such as condoms, a cap or a coil. If you are using a hormonal
contraceptive like the Pill, your doctor may take samples of your
blood to check the level of Lamotrigine tablets. If you plan to
start using a hormonal contraceptive, talk to your doctor, who
will discuss suitable methods of contraception with you.
Lamotrigine tablets can also affect the way hormonal
contraceptives work, although it’s unlikely to make them less
effective. If you are using a hormonal contraceptive and you
notice any changes in your menstrual pattern, such as
breakthrough bleeding or spotting between periods, tell your
doctor. These may be signs that Lamotrigine tablets are
affecting the way your contraceptive is working.

Pregnancy and breast-feeding
If you’re pregnant, think you may be pregnant, or are
planning to have a baby ask your doctor or pharmacist for
advice before taking this medicine.

Someone who has taken too many Lamotrigine tablets may
have any of these symptoms:
• rapid, uncontrollable eye movements (nystagmus)
• clumsiness and lack of co-ordination, affecting their balance
(ataxia)
• heart rhythm changes (detected usually on ECG)
• loss of consciousness, fits (convulsions) or coma.
If you forget to take Lamotrigine tablets:
Don’t take extra tablets or a double dose to make up for a
forgotten dose.
If you have missed taking a dose of Lamotrigine tablets:

It’s important that you do this.
Don’t stop taking Lamotrigine tablets without advice
Take Lamotrigine tablets for as long as your doctor
recommends. Don’t stop unless your doctor advises you to.
If you’re taking Lamotrigine for epilepsy
To stop taking Lamotrigine tablets, it is important that your
dose is reduced gradually, over about 2 weeks. If you
suddenly stop taking Lamotrigine tablets, your epilepsy may
come back or get worse.
If you’re taking Lamotrigine for bipolar disorder
Lamotrigine may take some time to work, so you are unlikely to
feel better straight away. If you stop taking Lamotrigine, your
dose will not need to be reduced gradually. But you should still
talk to your doctor first, if you want to stop taking Lamotrigine.
4. Possible side effects
Like all medicines, Lamotrigine tablets can cause side effects,
but not everyone gets them.
Allergic reaction or potentially serious skin reaction, get
a doctor’s help straight away.
A small number of people taking Lamotrigine tablets have an
allergic reaction or potentially life-threatening skin reaction,
which may develop into more serious problems if they are not
treated.
These symptoms are more likely to happen during the first few
months of treatment with Lamotrigine, especially if the starting
dose is too high or if the dose is increased too quickly or if
Lamotrigine is taken with another medicine called valproate.
Some of the symptoms are more common in children, so
parents should be especially careful to watch out for them.
Symptoms of these reactions include:
• skin rashes or redness, which may develop into
life-threatening skin reactions including widespread rash with
blisters and peeling skin, particularly occurring around the
mouth, nose, eyes and genitals (Stevens-Johnson
syndrome), extensive peeling of the skin (more than 30% of
the body surface – toxic epidermal necrolysis) or extended
rashes with liver, blood and other body organs involvement
(Drug Reaction with Eosinophilia and Systemic Symptoms
which is also known as DRESS hypersensitivity syndrome)
• ulcers in the mouth, throat, nose or genitals
• sore mouth or red swollen eyes (conjunctivitis)
• high temperature (fever), flu-like symptoms or
drowsiness
• swelling of the face, swollen glands in your neck, armpit, groin
• unexpected bleeding or bruising, or your fingers turning blue
• sore throat, or more infections (such as colds) than usual
• increased levels of liver enzymes seen in blood tests
• an increase in a type of white blood cell (eosinophilia)
• enlarged lymph nodes
• involvement of the organs of the body including liver and
kidneys.
In many cases, these symptoms will be signs of less serious
side effects. However, you must be aware that they are
potentially life-threatening and can develop into more serious
problems, such as organ failure, if they are not treated. If you
notice any of these symptoms, see a doctor at once. Your
doctor may carry out tests on your liver, kidneys or blood, and
may tell you to stop taking Lamotrigine tablets. In case you have
developed Stevens-Johnson syndrome or toxic epidermal
necrolysis your doctor will tell you that you must never use
lamotrigine again.
